There is no super speedy way to train unless you hack. I suggest registering the vs. seeker and going across the region battling everyone you can. You could always put your golduck in your first slot and give your weaker Pokemon the EXP. Share (obtained from one of Professor Rowan's aids) and battle the Elite Four over and over again; however, this will lower your EV. stats (effort values.)

No.
Actually you can't catch a lickitung so you must first get a Golduck then go to fuchsia city go west and into the big building go upstairs and trade you Golduck for the guy's Lickitung.
In Pokemon Ranger, you will not be able to find Golduck. You won't be able to find a Psyduck either.
